Letters Patent N 97,104, dated November 23, 1869.

IMPROVEMENT IN HARROWS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that we, Jons H. MILLER and F. A. Pioxnmxc, ot' Niantie, county of Macon, and State 01' Illinois, have invented a new and useful Improvement in l-larrows; and we do hereby declare the following to bc a full, clear, and exact description thereof, whereby others skilled in the art may make and use the same, l'efll'tlltfi being bad to the accompanying drawings, forming part of thisspecificntion.

This invention relates to a new and useful improvement in barrows, \rherebyihc parts which Harry the hnrrow-teeth are made adjustable, so that obstructions may be avoided, and so that the burrow will adjust itself to the surlilce of the ground over which it passes; and

It consists in the construction and arrangement hereinafter described. 1

In the accompanying drawings- Figure l is a top or plan view of the barrow.

Figure 2 is a rear-end .eleyation.

.Similar letters of reference indicate.corresponding parts.

A is the central bar, which extends the whole length of the barrow, to the front end of which the power is applied.

This bar is framed in two parts, which are hinged together, as seen at B, so that the rear end of the harrow may be raised by the driver for passing obstructions, and-for adjusting itself to the surface of the ground.

There may be burrow-teeth in this central bar, if desired.

0 G C 0 represent four rails, which carry the barrow-teeth.

These rails are jointed together, as seen at-D -D,

I and are jointed to both parts of the central bar A at To thcfin'wnrd or main portion of the bar A two standardsare attached, which extend up, as seen in fig. 2, marked F, and supported by them is a roller or Windlass, G.

H H represent the handles, which are attached to this windlass, so that the Windlass may be turned thereby.

11 represent chains or ropes, which are attached to the rails, near the joints D D, on each side of the barrow, and are connected with the windlnss by means of transverse hooks and guides, as seen at J J, tig. 1.

The windlass turns on pivots in the stands, as seen in fig. 1; and them'rangemcnt is such that when the driver, by means of the.- handles, turns the Windlass,

either side of the barrow may be raised for passing over-stones, roots, or other obstructions.

The sides of the barrow, or either of them, may be raised up and secured in an inclined position, by fastening them to the Windlass, so that. the burrow may be passed between rows of corn, or other crops growing in rows in the field.

In harrowing the ground, the flexibility of the bar-- row, caused by the hinged joints E, D, and B, will allow it to adjust itself to the inequalities of the ground.

K represents a transverse head-piece on the bar A, for the protection of the joints E In,

L is a hook, for the double-tree, for attaching the team.

M is a handle, attached to the bar A, for raising the rear end of the barrow.

\Ve do not confine ourselves to thc particular details as regards the construction of our barrow, but to the form and general construction, whereby itis so arranged that it may be so contracted in .width to adapt it to corn cultivation, and so that; it will adapt itself to the shape ot'tho ground over which it. passes, and also so that its sides or rear may be raised at will for avoiding obstructions, as before stated.

Having thus described our invent-ion,

\Ve claim as new and useful, and desire to secure by Letters Patcnt- 1. The combination of the toothed bars 0 C, central bar A, joint-ed connections D E B, and Windlass G, substantially as described.

2. The windlass G, and-the mode of raising the sides of the barrow, substantially as described.
